ERROR-408: MLLP Connector error; Please help

[fqian]

Hello,

We had a few error messages from Mirth 1.6 when sending HL7 files as shown below:

An error occurred in Mirth
ERROR-408: MLLP Connector error;
ERROR MESSAGE: Timeout waiting for ACK

But our clients on destination side confirmed us that they had no problem getting the result for those files. But it is really annoying and getting more such cases after we upgrade to 1.7.

Any idea?

Thank you!

Set your ACK timeout to 0 if you don't care about ACKs. Increase the ACK timeout if you want them. The network is probably just slow and takes a while to ACK back.

Thank you for your help. After we increase the ack timeout to 10,000 from 5,000 ms, it fixed the problem.

Perhaps your dest app is not answering an ACK. Disable the ACK wait, or use a sniffer to check what is sending back your destination.

Hi,
I am facing the same problem of getting the timeout error message. i have a LLP listener source that has two destinations. One is javascript writer destination that generates an acknwoledtement message and puts that message into responseMap like this:

responseMap.put("javascript_writer_destination",me ssageObject.getEncodedData());

The response is returned to the channel that is actually sending the HL7 message through LLP Sender as destination. Both, the sending and receiving channels are on the localhost.
I have disabled firewall as well to avoid any port blocking issue. I am using mirth 2.0.1
Please help!

I also had success (finally!!) after increasing from 5000 ms to 10000 ms. Also works if I select the "Ignore ACK" checkbox.

Thanks!!
